Unfortunately, cats can't tell us where or when it hurts. Some symptoms and behaviors are obvious: diarrhea, vomiting, coughing, sneezing, runny nose or eyes, and trouble using the litter box. There are other, more subtle, physical and behavioral indications that a visit to the vet might be in order.

Take note if your cat does any of the following:

Misses more than one meal

Shows a sudden change in eating habits

Stops using the litter box

Has a distant, depressed look in his or her eyes

Develops puffiness or a lump under the skin

Hides for more than a day

Becomes suddenly short-tempered or intolerant of attention

Shakes his or her head frequently

Changes his or her routine or loses interest in his or her favorite games
